- (void)creatPlistFile{
    NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
    NSString *path = [array objectAtIndex:0];
// 拼接phoneContact.plist时，有的Xcode不加/也行

plistPath = [path stringByAppendingString:@"/phoneContact.plist"];

    NSFileManager *fileManager = [[NSFileManager alloc]init];
    if (![fileManager fileExistsAtPath:plistPath]) {
      BOOL isOk = [fileManager createFileAtPath:plistPath contents:nil attributes:nil];
        if (isOk) {
            NSLog(@"创建成功");
        }
        else{
            NSLog(@"创建失败");
